Ha Thor wot are you like?! I couldnt imagine anyone in the world describing it as superb - not even Jason Statham's mum telling her neighbour over the fence. I think it could probably be described as mildly entertaining tosh.
Well, I think a great B monster movie can be just as 'superb' as a deep psychological drama by Bergman or an essay on alienation by Antonioni. Just for different reasons. .
"...Well, Ethel, my boy Jason has just finished his latest film in Hollywood about a giant shark 5 times bigger than a bus, i mean.. its complete B movie silly exaggerrated garbage, but i think its superb, in its own way, of course.."
